Alternatively, it is configured to be activated by remote control.

Next, the operation of the apparatus for cutting frozen fish, etc. according to the present invention constructed as described above will be explained with reference to a cutting example shown in FIG.

First, extend the clamp cylinder 42 and move the movable arm 4.
1 is raised, the object W to be cut such as sliced frozen fish is placed on the fixed arm 39, and the bit 37 is applied to the center of the object W, and then
The clamp cylinder 42 is contracted, the movable arm 41 is lowered, and the center of the workpiece W is clamped with two upper and lower pins 38 and 37 (see FIG. 4).

Next, the direction change motor 35 is activated to direct the saw 29 to the left in FIG. 2 while keeping it vertical, and the Y-axis servo motor 9 is activated to move the Y-axis holder 10 to the right in FIG. 1. After the X-axis servo motor 5 is operated to move the X-axis holder 6 to the right in FIG. Place it at the starting position Sl in the figure.

After the above preparatory work is completed, the cutting motor 30 is operated to vibrate the saw 29 up and down, and the cylinder 22 is operated to give reciprocating motion to the frame 19, causing the saw 29 to reciprocate. Simultaneous operation of the X-axis servo motor 5 and Y-axis servo motor 9 moves the saw 29 along the skin of the object to be cut (frozen fish sliced into rings) W, and the direction of the saw 29 is changed by the operation of the direction change motor 35. Gradually change direction.

By this operation, the object W to be cut is cut along the line (A).

Next, the saw 29 is moved to the St position of the workpiece W by the operation of the X-axis servo motor 5 and the Y-axis servo motor 9, and the saw 29 is directed to the center of the workpiece W by the action of the direction change motor 35, and the saw 29 is moved to the X position again. Simultaneous operation of the axis servo motor 5 and Y-axis servo motor 9 moves the saw 29 toward the center of the object W to cut the a1 line. a. After cutting the wire, pull out the saw 29 from the workpiece W in the radial direction until it leaves the outer periphery, move it in the circumferential direction and place it at position S3, and cut the wire in the same manner as above. disconnect. In this way a,
After cutting the ~an wire to make a 180 degree radial cut in the surface layer of the object W, the wire (b) is cut in the same manner as (a) cutting the wire. Thereafter, the same operation is repeated to cut the left half of the object W as shown in FIG. 5. Next, the rotation servo motor 43 is activated to rotate the workpiece W by half a rotation, and the remaining portion is cut.

In addition, in the above example, the workpiece W is fixed and the saw 29 is moved by the operation of the X-axis servo motor 5 and the Y-axis servomotor 9 to cut the workpiece W. It is also possible to cut lines such as (a) and (b) by rotating the workpiece W around the bits 37 and 38 by the rotating servo motor 43 while moving the workpiece W up and down at the cutting position. In this case as well, the direction of the saw 29 is changed by the direction changing motor 35.
to gradually change the movement in the Y-axis direction using the Y-axis servo motor 9.
It is necessary to do this by operating the When rotating the object W to be cut, it is also possible to cut the object W by 360 degrees without cutting the line ζ4) or (b) by 180 degrees. Further, the relative movement of the saw 29 from the S9 position to the S8 position can also be performed by rotating the wave cutting object W by the rotating servo motor 43. In this case, the object W to be cut is rotated in the circumferential direction without any load being applied thereto, so rotational indexing can be performed reliably and reliably, and the bits 37 and 38 will not be damaged.

Moreover, although the example in which the saw 29 is vertically cut to cut the object W to be cut has been described above, the servo motor 14 for vertical movement is
The saw 29 is made horizontal by the operation of the rotating servo motor 17 and the workpiece W is cut horizontally to make finer cuts, or the workpiece W is tilted at an appropriate angle to adjust its shape and installation. It can also be cut in various ways depending on the posture.
